Ariana and Frankie Grande honor their late grandfather by obeying his last wishes

Ariana Grande has officially executed what a complete professional looks like, as the singer continues to fulfill her public commitments in late of her grandfathers passing.

As reported earlier, the ”Problem” singer announced her grandfathers passing early Wednesday morning on Twitter. It was only hours later that producers slipped brother Frankie Grande a note informing him as well of the news.

Us Weekly reports that Ariana did follow through with her prior commitment for Wednesday, appearing on Good Morning America, and managed to keep herself together as much as one could.

Afterwards, she wrote, “Thaaaanks to my best friends who stayed up with me all night talking and helped me pull myself together temporarily this am. Only reason I made this twelve hour trip is grandps told me he wanted me to always be professional & fulfill my business commitments."

Ariana has been sharing photos of her and her grandfather on Instagram and Twitter to demonstrate her love and loss for her new star in the sky.

Her final tweet came after watching her brothers eulogy from Big Brother After Dark as he will be remaining in the house and continuing to compete, as were his grandfathers and family’s wishes, which read, “watching @frankiejgrande talk abt grandps after reading our letter on the live feed. sobbing / laughing hysterically. love u frankie so much.”
